When attempting to start a torrent with a .torrent file whose filename contains CJK characters (and possibly other international characters), qBittorrent throws an error saying "I/O Error: The torrent file does not exist.". CJK characters in the names of the torrents themselves and the files within the torrent work fine, it's just the initial opening of a .torrent file that fails.

This issue is happening on Windows with v3.0.5.

Could we get such a torrent to debug?

Also, this is likely specific to Windows.

Is this related, by any chance, to this? -> https://github.com/qbittorrent/qBittorrent/issues/135

It's not specific to any particular torrent, so you can trigger the issue by renaming a torrent (my work-around for the problem is renaming the torrents that won't open to random strings of Latin characters). Try copy-pasting this: ファイル

Also, I just saw that if you attempt to open such a torrent by double-clicking on it while qBittorrent is not running, qBittorrent will start and correctly open the torrent, but if you try again after the program is already running, it no longer works.

As for being related to that other bug, I don't know. I only ever see the issue when I try to open files with CJK filenames, not every time the program is launched.

This is useful. I can reproduce on Windows XP. I am not sure if this is a compilation problem or qbittorrent's/qt's problem. I'll try to investigate more but it will probably take a while(a few days) because I am busy with real life...
